Kucherov, one of the front-runners for the NHL MVP award, has 110 points through 69 games. Lecavalier held the previous franchise record, finishing with 108 points when he had 52 goals and 56 assists during the 2006-07 season.

The record-setting point came on Kucherov's 32nd goal. He was alone at the top of the crease when he got a pass from Brayden Point and flipped the puck over Bernier at 11:56 of the first period.

"It's special for me and my family, definitely," Kucherov said. "I don't think many people believed in me and I'm just trying to keep proving them wrong. I'm happy for myself and thanks to all the guys for helping me out. Without them I wouldn't have this much success."

Said Lecavalier in a statement: "Kuch is an unbelievable player. He is so dominant and talented that it is no wonder he broke my Lightning record for most points in a season. I'd like to personally congratulate Nikita for the accomplishment."

The Lightning became the first team this season to clinch a playoff berth after Montreal lost to Anaheim late Friday. It marked the second quickest in terms of games (68) needed to clinch a playoff spot since 2005-06.

But Tampa Bay feels as if there is plenty to accomplish in the final few weeks of the season.

"We've talked about this a lot, to have consistency in our game," coach Jon Cooper said. "I thought tonight ... we really didn't give them much. I really liked the way we played from start to finish."

McDonagh also scored in the first on a wrist shot from the center point, helping Tampa Bay build a 2-0 lead.

The two-goal advantage held up until late in the second period when Vanek deflected a Niklas Kronwall pass past Domingue for a power-play goal with 3.1 seconds left.

Kucherov also scored on a one-timer from the right circle 13:53 into the third for his 33rd multipoint game of the season. Mantha got one back for Detroit with 56 seconds left, but Tampa Bay held on.

"It's really frustrating," Mantha said of the losing streak to the Lightning. "I mean it (stinks) that we can't win against these guys. I don't know what it is. I mean (Bernier) played an unbelievable game tonight. He probably saved four or five goals against and we couldn't build anything offensively."
